Hi! I'm Ariel.
before we start ~

This is the slow version of a portfolio. I wanted somewhere I could put the work, the music, and the books all in one place — without pretending they're separate things.

how to read this:
  • tap any tab on the left to flip there
  • ← → keys turn pages, like a real one
  • scribbles in lilac are mine, in the margin
  • sticky notes mean: don't miss this bit

P. 01 CHAP · about me ~

Curious by nature,
strategic by habit.

I'm a second-year Degree Apprentice in Digital & Technology Solutions (Data Analysis), based in the UK, working at Ricoh UK in a pre-sales and consulting capacity — leading commercial discovery, shaping bids, and designing Power BI data architecture.

Alongside my apprenticeship, I'm building cumula — an AI-powered GCSE revision app for UK students that automates the diagnostic loop a good tutor runs in their first session. I started my first ecommerce business at 15 — the builder instinct has never really switched off.

Outside of work, I find balance through piano, books, and long walks. I believe the most interesting people never stay inside one box.

P. 07 ~ beyond work ~

Music, discipline,
and play.

Piano · ABRSM
↳ patient repetition, slight edge.
P. 08

I've been playing piano to Grade 5 level — a discipline that quietly mirrors the way I approach everything else: patient repetition, structured improvement, and the satisfaction of something that clicks after practice.

Music is where I step away from screens. It keeps my thinking balanced and reminds me that not everything worth doing has a metric attached.

Currently working through some Liszt and Chopin nocturnes — because apparently I enjoy making things harder for myself.
